How to File a Complaint Against CITGO
Customers experiencing a problem involving a CITGO-branded station, fuel quality, loyalty program or consumer interaction should identify the specific station and transaction before contacting the company.
Step 1: Contact the Station
If the issue occurred at a CITGO-branded gas station, contact the location and ask to speak with the station owner or manager because individual locations are independently operated.
Step 2: Keep the Receipt
Retain the fuel receipt, transaction record and station address so CITGO can identify the branded location.
Step 3: Contact CITGO Customer Service
Call 1-800-423-8434, Option 1 and provide the station, transaction and complaint information.
Step 4: Submit the Online Contact Form
Use CITGO’s official Contact Us page and select the topic that best matches the complaint.

If the initial response does not resolve the concern, follow up through CITGO Customer Service and provide the prior case information.
Step 7: Request Additional Review
Ask whether the issue can be reviewed by the appropriate fuels, branded-retail or corporate team.
Step 8: Handle Emergencies Separately
For a pipeline or terminal emergency, call 1-800-471-9191 immediately rather than submitting an ordinary consumer complaint.
